We have a 2014 Winnebago(gas) with the Ford V10 engine. I tow a small Pontiac Vibe behind. When going down a long descent, I'm wondering what is the best way to go. I always have tow/haul mode engaged...
The Triton V10 makes most of its power in the higher RPM range, so the high revs may sound bad, but really it's just the engine doing its thing that its designed to do. And, as I understand it, the tow/haul mode is also designed to change the shift points to assist in towing by putting the engine in optimum gear range for maximum power and for geared slowing to help preserve braking capability.
